Ya boat launches are easy ... obviously if you wanna Launch like a monkey in sizable swell you will get a drilling!!! ... I shoredive all the time it depends what i want... if i want an easy dive i sit on a point...(garick and pelagic) if i wanna go to gym... i open reef dive (reef fish) ... i dont have the balls to go out in 4-6 foot waves... then i surf ...its more pleasant!
RULE number one if you see dolphins the pelagics are gone/eaten!
Rule number 2, if you dive in the green with 2meters or less you wont see the pelagics in time, specially the garrick they fast buggers.
Rule number 3 if you stay in long enough it gets very productive ...
